Brief Summary

This is an open label, single-site, dose-escalation study in up to 18 participants with Relapsed or Refractory Multiple Myeloma, Acute B-Cell Leukemia, and B-Cell Lymphoma. This study aims to evaluate the safety and efficacy of the treatment with Anti-BCMA and CD19 CART

Conditions

Lymphoblastic Leukemia; Relapsed or Refractory Multiple Myeloma (RRMM)

Keywords

B-cell lymphoma; Relapsed or Refractory Multiple Myeloma; Acute B-Cell Leukemia

Outcome Measures

Primary Outcomes (1)

The AEs will be assessed according to the 2019 Consensus on Cytokine Release Syndrome and Immune-cell-associated Neurotoxicity published by the American Society of Transplantation and Cell Therapy (ASTCT), the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0 and EBMT 2019 consensus.

  up to 2 years

Secondary Outcomes (4)

• 2.The persistence, accumulation, and migration of CART cells

  up to 2 years

• Progression free survival (PFS)

  up to 2 years

• Overall survival (OS)

  up to 2 years

• Objective Response Rate (ORR)

  up to 2 years

Study Arms (1)

Experimental: Anti-BCMA and CD19 CART

EXPERIMENTAL

Patients will receive a lymphodepletion chemotherapy with cyclophosphamide and fludarabine before CART infusion. A dose of Anti-BCMA and CD19 CART will be infused on day 0.

Drug: Anti-BCMA and CD19 CART cells will be injected intravenously on a one-time basis

Interventions

Anti-BCMA and CD19 CART cells will be injected intravenously on a one-time basis DRUG

A single intravenous infusion of anti-BCMA and CD19 CART cells (dose-escalating infusion of 1.0-5.0 x10\^5 CART cells/kg）.

Experimental: Anti-BCMA and CD19 CART

• Patients diagnosed with acute B-cell leukemia: Patients who have achieved relapse after achieving remission after prior chemotherapy; or patients who have failed to achieve remission (\<5% bone marrow blasts or persistent extramedullary or central nervous system disease) after 2 prior cycles of induction chemotherapy, or who still maintain MRD.
• Multiple Myeloma: Patients with confirmed diagnosis of multiple myeloma and patients with relapsed or refractory multiple myeloma according to IMWG 2016 diagnostic criteria.
• For patients with B-cell lymphoma, according to the recommendations for initial evaluation, staging, and response evaluation of Hodgkin and non-Hodgkin lymphoma (2014 edition), at least one measurable lesion in the baseline period, i.e., lymph node lesions with a length diameter of \> 15 mm, or an extranodal lesion with a length diameter of \> 10 mm according to PETCT or CT imaging;
• For patients with B-ALL, the proportion of bone marrow primitive and naïve lymphocytes in the screening period ≥5%;
• CD19 expression of tumor cells confirmed by flow cytometry or immunohistochemistry: the proportion of CD19 cells detected by peripheral blood flow cytometry in patients with B-ALL was ≥30%, and the proportion of CD19 cells in patients with B-cell lymphoma was positive by immunohistochemistry;
• Adequate function of vital organs: liver function satisfies ALT≤3×ULN, AST≤3×ULN; serum creatinine≤140μmol/L; Total bilirubin ≤ 2× ULN, and total bilirubin ≤ 3.0× ULN for patients with Gilbert syndrome; Haemodynamically stable and left ventricular ejection fraction (LVEF) ≥45% as determined by echocardiography or multichannel radionuclide angiography (MUGA); No active pulmonary infection, transcutaneous arterial oxygen saturation ≥92% in non-oxygen-based state;
